The formula to calculate the Pressure Intensity is:
\[ pi = \frac{Wt}{\pi \cdot R^2} \]
The Pressure intensity at a point is defined as the external normal force per unit area. The SI unit of pressure is Pascal.
Let's assume the following values:
Using the formula:
\[ pi = \frac{24}{\pi \cdot 3.3^2} = 0.701509391038657 \text{ Pa} \]
